[Insight-users] GDCM: dicom directory and filenames

[Mathieu Malaterre]

George,

	If you use ctest to run the test you can pass in the '-V' flags to see 
how the test works. For instance:

$ ctest -R GDCMSeriesReadImageWrite -V -N 
 
        Test project
Changing directory into 
/home/mathieu/Dashboards/MyTests/Insight-gcc/Testing/Code/IO
   1/  1 Testing itkGDCMSeriesReadImageWrite

Test command: 
/home/mathieu/Dashboards/MyTests/Insight-gcc/bin/itkGDCMSeriesReadImageWrite 
/home/mathieu/Dashboards/MyTests/Insight/Testing/Data/Input/DicomSeries 
/home/mathieu/Dashboards/MyTests/Insight-gcc/Testing/Temporary/itkGDCMSeriesReadImageWrite.vtk 
/home/mathieu/Dashboards/MyTests/Insight-gcc/Testing/Temporary


	So you see that the input directory is :

/home/mathieu/Dashboards/MyTests/Insight/Testing/Data/Input/DicomSeries

	And the output directory -as you mention- is :

/home/mathieu/Dashboards/MyTests/Insight-gcc/Testing/Temporary


	One of the two test is disable because we cannot create new directory 
(might be fixed in the future). A test assume you have write access to a 
particular directory for writting output images. In this case:

/home/mathieu/Dashboards/MyTests/Insight-gcc/Testing/Temporary

	Now if you would run twice the test specifying the same output 
directory the images will be overwritten. One simple way to solve it 
directly in the test is to use the itksys::SystemTools::Mkdir and create 
a subdir for example:

/home/mathieu/Dashboards/MyTests/Insight-gcc/Testing/Temporary/GDCM
